Holes I! may be formed in the pin member 6 for attachment ofthat member to a garment or other article to which the fastener is to beapplied.

It will be understood that the present invention renders it possible toapply separable end fittings to fasteners of which the fastener membersmay be of extremely small dimensions without attendant disadvantages ofdimculty in manipulation. Furthermore,- the invention is particularlyapplicable to fasteners made of plastic materials and permits of theengaging portions of the open-end fittings being made of dimensionsnecessary for adequate strength; The separable end fitting may be madein any desired manner depending to some extent on the nature of thematerial to be employed, although in the case 'of plastic material amolding or casting process is in most cases preferred.

WhileIhave shown and described in this ap-v plication, one embodimentwhich my invention may assume in practice, it will be understood thatthis embodiment is merely for the purposes of illustration, and thatvarious other forms may be devised within the scope of my invention asdefined in the appended claims.

What I claim as my invention is:

1. In a slide fastener including two stringers having fastener elementson their adiacent edges, and a slider mounted on the elements to'openand close the fastener; a separable end connection for the stringerscomprising a socket memstringer at its outer edge,

2,2;239 v v 4 her attached to one stringer at its inner edge,

and a pin member attached to. the opposite said socket member extendinglaterally from its'stringer beyond the path of the slider bodyyand asocket in the extension of said socket' member beyond said path, adaptedto receive said pin to make the connection for the ends of the fastenerstringers to one side of the path of the slider.-

2.1L slide fastenerseparable end connection as defined in claim 1 inwhich the pin member which is located to one side of the path of theslider has a lateral extension toward the edge of its stringer tostiffen the end of the stringer.

3. A slide fastener separable end connection as defined in claim 1 inwhich said pin member has a lug extending therefrom, said lug beingshaped to form the lowermost fastener element on the same stringer.

4.;In a slide fastener including two stringers having fastener elementson their adjacent edges, and a slider mounted on the elements to openand close the fastener; a separable-end connection for the stringerscomprising a socket member attached to one stringer at its inner edge,the socket portion of which extends so far enough beyond the stringerthat the socket is beyond the path 'of movement of the slider, and amember attached to the outer edge of the other stringer cooperating withthe socket to hold the stringers together, said. member having a pinportion engageable with the socket outwardly of the path of movement ofthe slider and an upward extension extending parallel .to the fastenertherefrom a suflicient distance to enable free movement of the sliderbetween the fastener elements and extension.
